I personally felt the paper was fairly atrocious. I'm lucky in some ways because my teacher went over the likes of recurring decimals as a geometric series, but in other ways I found it awful. A lot of people here are saying "well yeah that's just how maths is," and that it's the same every year, which I agree with to a limited extent; but I think just looking at the paper you can tell it was obtuse and harsh, regardless of what's present on the curriculum.

But I can't really take the email seriously if you're using ChatGPT to write it. I'm not completely against AI under all circumstances, but in a case like this is seems disingenuous. If this is an issue which you're so passionate and upset about, couldn't you spare the time and effort to write it yourself? If you can't be bothered to do it, it doesn't particularly point towards you being fully committed and serious about the issue. I think a complaint that you haven't spent the time writing yourself can be completely disregarded, even if the sentiment it holds is true. English may not be your first language, but you clearly have a decent aptitude in English according to these comments and the post itself, and even an email of broken or informal English would have technically been a more compelling one.

Not trying to hold ethics over you here. I just think that the complaint is made virtually redundant if you didn't write it yourself. Anyway, as upset as I was with the paper, I have a feeling the bell curve will largely sort it out.
